The utility model discloses a glazed tile step forming device comprising a frame body, a stamping die core assembly, at least one first oil cylinder, a middle plate, and at least one second oil cylinder fixed on the middle plate. The frame body comprises a bottom plate, at least one support pillar fixedly connected to the bottom plate and a top plate fixedly connected to the tops of the support pillars. The stamping die core assembly comprises a first upper die, a first lower die, a second upper die and a second lower die. The first upper die cooperates with the first lower die and the second upper die cooperates with the second lower die. The dies are all matched with glazed tiles. The first oil cylinder comprises a first piston rod. The lower end of the first piston rod is fixedly connected with the middle plate and can drive the middle plate to slide vertically. The second oil cylinder comprises a second piston rod. The first upper die is fixed connected to the bottom of the middle plate. The second upper die is fixedly connected with the lower end of the second piston rod. The first lower die and the second lower die are fixedly connected to the bottom plate. The glazed tile step forming device is long in service life, has fewer vulnerable parts, is high in yield and can be used for stretching deep steps.
